Shrub climbing rose plant named `Meitosier`

ABSTRACT

A new and distinct variety of Shrub Climbing rose plant is provided which forms attractive large lightly-fragrant light Mandarin Orange blossoms generally having the configuration of old roses. The blossoming is abundant and the plant reflowers well. The vegetation is vigorous and the plant possesses a climbing growth habit. The plant exhibits very good disease resistance particularly with respect to Marssonina and Black Spot.

SUMMARY OF THE INVENTION

The new variety of Shrub Climbing rose plant of the present inventionwas created by artificial pollination wherein two parents were crossedwhich previously had been studied in the hope that they would contributethe desired characteristics. The female parent (i.e., the seed parent)was the product of the pollination of the Meipalsar variety(non-patented in the United States) and the Golden Showers variety (U.S.Plant Pat. No. 1,557). The male parent (i.e., the pollen parent) of thenew variety was the Light Konigin Lucia variety (non-patented in theUnited States). The parentage of the new variety can be summarized asfollows:

    (Meipalsar×Golden Showers)×Licht Konigin Lucia.

The seeds resulting from the above pollination were sown and 116 smallplants were obtained which were physically and biologically differentfrom each other. Selective study resulted in the identification of asingle plant of the new variety.

It is found that the new variety of Shrub Climbing rose plant possessesthe following combination of characteristics:

(a) forms attractive large lightly-fragrant light Mandarin Orangeblossoms having an old-rose configuration,

(b) exhibits a propensity for climbing,

(c) exhibits a good ability to reflower, and

(d) is particularly suited for growing as ornamentation in thelandscape.

The new variety meets the needs of the horticultural industry. It can begrown to particular advantage as attractive ornamentation in parks,gardens, public areas, and residential landscapes.

The characteristics of the new variety have been found to be homogeneousand stable and are strictly transmissible by asexual propagation carriedout in France (e.g., by budding, grafting, and cuttage) from onegeneration to another.

The new variety has been named the Meitosier variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying photograph shows as nearly true as it is reasonablypossible to make the same, in a color illustration of this character,typical specimens of the plant parts of the new variety. The rose plantsof the new variety described herein were three years of age and wereobserved during September while budded on Rosa froebelii understock andgrowing outdoors at Le Cannet des Maures, Var, France.

DETAILED DESCRIPTION

The chart used in the identification of the colors is that of The RoyalHorticultural Society (R.H.S. Colour Chart). The terminology precedingthe numbered reference to the chart has been added to indicate thecorresponding color in more common terms. The description is based onthe observation of three year-old specimens of the new variety duringJune while growing outdoors when budded on Rosa froebelii understock atLe Cannet des Maures, Var, France.
